Default Re: Marconi C100 B28 vs. Eddystones

Here we go: apologies for the crap phonecam resolution...

Remember that this analysis was done from the perspective of commercial point-to-point HF circuits, not ad-hoc ham-radio operation.

They don't mention the instability and wobbliness in the face of mains-voltage fluctuations, or the LO drift over several hours as the receiver warms-up after a cold-start. I guess 'commercial' applications had stable mains and involved receivers that were not subject to turning-on-and-offable thermal-cycling.
